It isn't directly across the street, it's more closer to the H-Mart shopping center which is 2-3 blocks away.
Best place to get food is the H-Mart shopping center. There are 2 Vietnamese restaurants (Little Saigon and Pho & Cafe Anh Hong), an awesome Chinese dumpling spot (drawing a blank on the name), good Mexican (Don Memo) and a bunch of decent Korean food stalls in the upstairs shopping area of the H-Mart.
There is also Pica's for interesting pizza approximatelty 5 mins away on West Chester Pike, and a block away from Pica's is Cawley's for above average bar food/drinks and good Irish meals.
